My experience with block filler is much less satisfactory. Both blocks were
half filled. Worked great at Maxton (one mile). Survived the three mile
course at Bonneville, but developed to much heat on rear cylinders...lack of
proper cooling due to reduced capacity, I believe...on the five mile long
course and the motor self-destructed. BTW the temp gauge was up front and
didn't register the problem. There may be ways of re-routing coolant to
overcome this problem, but I'm not sure I want to experiment with it.
Can tell you that a 283 can be bored to 4" without a problem, or the need
for filler. Have run them well over 200 MPH in the past.
